Available in PDF, EPUB and Kindle. Book excerpt: Living amniotes—including all mammals, birds, crocodilians, snakes, and turtles—comprise an extraordinarily varied array of more than 21,000 species. Found in every major habitat on earth, they possess a truly remarkable range of morphological, ecological, and behavioral adaptations. The fossil record of amniotes extends back three hundred million years and reveals much about modern biological diversity of form and function. A collaborative effort of twenty-four researchers, Amniote Paleobiology presents thirteen new and important scientific perspectives on the evolution and biology of this familiar group. It includes new discoveries of dinosaurs and primitive relatives of mammals; studies of mammalian chewing and locomotion; and examinations of the evolutionary process in plesiosaurs, mammals, and dinosaurs. Emphasizing the rich variety of analytical techniques available to vertebrate paleontologists—from traditional description to multivariate morphometrics and complex three-dimensional kinematics—Amniote Paleobiology seeks to understand how species are related to each other and what these relationships reveal about changes in anatomy and function over time. A timely synthesis of modern contributions to the field of evolutionary studies, Amniote Paleobiology furthers our understanding of this diverse group.

Available in PDF, EPUB and Kindle. Book excerpt: An in-depth look at the origin and evolutionary radiation of the synapsids. About 320 million years ago a group of reptiles known as the synapsids emerged and forever changed Earth’s ecological landscapes. This book discusses the origin and radiation of the synapsids from their sail-backed pelycosaur ancestor to their diverse descendants, the therapsids or mammal-like reptiles, that eventually gave rise to mammals. It further showcases the remarkable evolutionary history of the synapsids in the Karoo Basin of South Africa and the environments that existed at the time. By highlighting studies of synapsid bone microstructure, it offers a unique perspective of how such studies are utilized to reconstruct various aspects of biology, such as growth dynamics, biomechanical function, and the attainment of sexual and skeletal maturity. A series of chapters outline the radiation and phylogenetic relationships of major synapsid lineages and provide direct insight into how bone histological analyses have led to an appreciation of these enigmatic animals as once-living creatures. The penultimate chapter examines the early radiation of mammals from their nonmammalian cynodont ancestors, and the book concludes by engaging the intriguing question of when and where endothermy evolved among the therapsids. “Ever since Nick Hotton’s book from the 1980s we have needed an update on the biology of therapsids, and it has been Anusuya Chinsamy-Turan and her students and associates who through their bone histological work have made the greatest progress in this field.” —Martin Sander, Steinmann Institute, University of Bonn “Forerunners of Mammals is full of meticulous detail . . . [I]t also contains a number of excellently rendered illustrations of some of the animals covered in the book, and the final chapter is a discussion of the evolution of endothermy that anyone with a background in biology might find of interest. . . . Recommended.” —Choice “Forerunners of Mammals will take interested readers beyond the classic jaw-to-ear appreciation of therapsids, towards a deeper appreciation of the ancestry of mammals.” —Journal of Mammalian Evolution “This volume represents a state-of-the-art contribution to our understanding of the paleobiology of how mammals arose, and what factors contributed to their evolutionary radiation and eventual success. It is highly recommended for anyone interested in these topics, and will be accessible to readers with minimal background in bone histology and synapsid paleontology.” —Quarterly Review of Biology

This book was released on 2015-08-11 with total page 487 pages. Available in PDF, EPUB and Kindle. Book excerpt: “The focus is the most severe mass extinction known in earth’s history. The science on which the book is based is up-to-date, thorough, and balanced. Highly recommended.” —Choice Today it is common knowledge that the dinosaurs were wiped out by a meteorite impact 65 million years ago that killed half of all species then living. It is far less widely understood that a much greater catastrophe took place at the end of the Permian period 251 million years ago: at least ninety percent of life on earth was destroyed. When Life Nearly Died documents not only what happened during this gigantic mass extinction but also the recent renewal of the idea of catastrophism: the theory that changes in the earth’s crust were brought about suddenly in the past by phenomena that cannot be observed today. Was the end-Permian event caused by the impact of a huge meteorite or comet, or by prolonged volcanic eruption in Siberia? The evidence has been accumulating, and Michael J. Benton gives his verdict at the end of the volume. The new edition brings the study of the greatest mass extinction of all time thoroughly up-to-date. In the twelve years since the book was originally published, hundreds of geologists and paleontologists have been investigating all aspects of how life could be driven to the brink of annihilation, and especially how life recovered afterwards, providing the foundations of modern ecosystems.

Available in PDF, EPUB and Kindle. Book excerpt: The Royal Society's Science Book of the Year "[A]n exuberant romp through evolution, like a modern-day Willy Wonka of genetic space. Gee’s grand tour enthusiastically details the narrative underlying life’s erratic and often whimsical exploration of biological form and function.” —Adrian Woolfson, The Washington Post In the tradition of Richard Dawkins, Bill Bryson, and Simon Winchester—An entertaining and uniquely informed narration of Life's life story. In the beginning, Earth was an inhospitably alien place—in constant chemical flux, covered with churning seas, crafting its landscape through incessant volcanic eruptions. Amid all this tumult and disaster, life began. The earliest living things were no more than membranes stretched across microscopic gaps in rocks, where boiling hot jets of mineral-rich water gushed out from cracks in the ocean floor. Although these membranes were leaky, the environment within them became different from the raging maelstrom beyond. These havens of order slowly refined the generation of energy, using it to form membrane-bound bubbles that were mostly-faithful copies of their parents—a foamy lather of soap-bubble cells standing as tiny clenched fists, defiant against the lifeless world. Life on this planet has continued in much the same way for millennia, adapting to literally every conceivable setback that living organisms could encounter and thriving, from these humblest beginnings to the thrilling and unlikely story of ourselves. In A (Very) Short History of Life on Earth, Henry Gee zips through the last 4.6 billion years with infectious enthusiasm and intellectual rigor. Drawing on the very latest scientific understanding and writing in a clear, accessible style, he tells an enlightening tale of survival and persistence that illuminates the delicate balance within which life has always existed.

This book was released on 2013-09-20 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Non-mammalian synapsids were the dominant terrestrial vertebrates from the Late Carboniferous to the Middle Triassic and play a key role in understanding the origin and evolution of mammals. Despite these facts and the outstanding fossil record of the group, early synapsids remain obscure. This book showcases the full breadth of contemporary research on non-mammalian synapsids, ranging from taxonomy and phylogenetics to functional morphology, biogeography, paleoecology, and patterns of diversity. It also underscores the importance and potential of studying non-mammalian synapsid paleobiology in its own right, not just in the context of mammalian evolution.​

Download or read book Semi aquatic Mammals written by Glynnis A. Hood and published by JHU Press. This book was released on 2020-10-13 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: A groundbreaking review of the seldom-studied semi-aquatic freshwater mammals, covering biology, behavior, and conservation. Semi-aquatic mammals are some of the rarest and most endangered mammals on earth. What binds them together in the minds of biologists, despite their diverse taxa and body forms, are evolutionary traits that allow them to succeed in two worlds—spending some time on land and some in the water. Semi-aquatic Mammals fills a crucial void in the literature by highlighting the important ecological roles and curious biology of these remarkable animals. In this unique book, wildlife ecologist Glynnis A. Hood presents the first comprehensive examination of a global suite of 140 freshwater semi-aquatic mammals. Each one has overcome the distinct ecological challenges of thriving in both aquatic and terrestrial habitats as part of everyday life. Covering millions of years, Hood's exploration begins with the extinct otter-like Buxolestes and extends to consider the geographical, physical, behavioral, and reproductive traits of its present-day counterparts. Hood explains how semi-aquatic mammals are able to navigate a viscous environment with almost no resistance to heat loss, reveals how they maintain the physical skills necessary to avoid predation and counter a more thermally changeable environment, and describes the array of adaptations that facilitate success in their multifaceted habitats. She also addresses specific conservation challenges faced by these mammals. Her analysis takes readers to the haunts of intriguing semi-aquatic mammals from around the world, • introducing the "paradoxical platypus," an Australian egg-laying monotreme that detects prey through electroreception • venturing into the swamps and mangroves of Southeast Asia, where fishing cats wave their paws above the water's surface to lure prey • trawling the streams and lakes of South America, where the female water opossum uses its backward-facing pouch to keep her babies warm during deep dives • spending time with species that engineer freshwater habitats into more productive and complex systems, including North American beavers and Africa's common hippopotamus Featuring award-winning artist Meaghan Brierley's stunning illustrations throughout, Semi-aquatic Mammals is an unparalleled reference on some of the world's most tenacious and fascinating mammals.

Download or read book The Transantarctic Mountains written by Gunter Faure and published by Springer Science & Business Media. This book was released on 2010-09-21 with total page 812 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a summary of the geology of the Transantarctic Mountains for Earth scientists who may want to work there or who need an overview of the geologic history of this region. In addition, the properties of the East Antarctic ice sheet and of the meteorites that accumulate on its surface are treated in separate chapters. The presentation ends with the Cenozoic glaciation of the Transantarctic Mountains including the limnology and geochemical evolution of the saline lakes in the ice-free valleys. • The subject matter in this book is presented in chronological order starting about 750 million years ago and continuing to the present time. • The chapters can be read selectively because the introduction to each chapter identifies the context that gives relevance to the subject matter to be discussed. • The text is richly illustrated with 330 original line drawings as well as with 182 color maps and photographs. • The book contains indexes of both subject matter and of authors’ names that allow it to be used as an encyclopedia of the Transantarctic Mountains and of the East Antarctic ice sheet. • Most of the chapters are supplemented by Appendices containing data tables, additional explanations of certain phenomena (e.g., the formation and seasonal destruction of stratospheric ozone), and illustrative calculations (e.g., 38Cl dates of meteorites). • The authors have spent a combined total of fourteen field seasons between 1964 and 1995 doing geological research in the Transantarctic Mountains with logistical support by the US Antarctic Program. • Although Antarctica is remote and inaccessible, tens of thousands of scientists of many nationalities and their assistants have worked there and even larger numbers of investigators will work there in the future.
